I would do that if I still had issues.  But since reducing the ring buffer
to 4700, and adding
kernel.shmall = 167772160
kernel.shmmax = 167772160
to systcl.conf in the backend, I no longer have any issues.
The backend log still spits out "Waited 0.2 seconds for data
#012#011#011#011to become available" constantly.
The frontend log is clean now.

I still sometimes get a very brief pause at the top or bottom of the hour.
Maybe 1/2 second.  But I only notice that maybe once a day.

why modding the systcl.conf changed things I do not know.  But if its not
broke, dont fix it.
